Description

Technical Field

[0001] This application relates to the technical field of testing machinery, and more particularly, to a flip fatigue testing device. Background Art

[0002] Currently, the fatigue resistance of a flip is an index parameter that must be detected when flip products leave the factory. In the prior art, there are usually the following two methods for flip fatigue testing. One is manual testing. Although it can perfectly reproduce the actions during flip use, it has low efficiency and high cost. The other is to use an existing fatigue testing machine, which can improve the flip efficiency and greatly save labor costs. However, the existing fatigue testing machines cannot well simulate the actual use process, and there is a large difference between the test results and the actual effects, with poor accuracy. Summary of the Invention

[0003] The purpose of the embodiments of this application is to provide a flip fatigue testing device, which can achieve the technical effects of cost savings, while improving the test efficiency and test accuracy.

[0004] The embodiments of this application provide a device including a base mechanism, a fixture mechanism, and a flip mechanism. The fixture mechanism is installed on the base mechanism and can move forward or backward along the base mechanism. A fixing member for fixing the cover to be tested is provided on the fixture mechanism. The flip mechanism includes a cover closing member and a cover opening member. The cover closing member and the cover opening member are arranged above the fixture mechanism. The cover closing member is used to close the cover of the cover to be tested when the fixture mechanism moves backward, and the cover opening member is used to open the cover of the cover to be tested when the fixture mechanism moves forward.

[0005] In the above implementation process, the fixture mechanism and the flip mechanism are installed on the base mechanism, and the fixture mechanism can move forward or backward along the base mechanism. During the forward or backward movement of the fixture mechanism, through the mutual cooperation of the cover closing member and the cover opening member in the flip mechanism, the flip operation is performed on the cover to be tested. During the continuous forward and backward movement of the fixture mechanism, the cover to be tested is continuously opened and closed, so as to perform fatigue testing on the cover to be tested. This flip fatigue testing mechanism simulates the actions of the cover to be tested during actual use, thereby achieving the technical effects of cost savings, while improving the test efficiency and test accuracy.

[0006] Further, the cover closing member includes a cover closing rod, and the cover closing rod is used to close the cover of the cover to be tested in the open state when the fixture mechanism moves backward.

[0007] In the above implementation process, the lid-closing member performs a lid-closing operation on the lid to be tested through a lid-closing rod: when the jig mechanism retracts, the lid of the lid to be tested in the open-lid state is blocked by the lid-closing rod. Thus, when the jig mechanism continues to retract, the lid of the lid to be tested closes under the action of the lid-closing rod, completing the lid-closing operation of the lid to be tested.

[0008] Further, the lid-opening member includes a lid-opening hook, which is used to open the lid to be tested in the lid-closed state when the jig mechanism advances.

[0009] In the above implementation process, the lid-opening member performs a lid-opening operation on the lid to be tested through the lid-opening hook: when the jig mechanism advances, the lid of the lid to be tested in the lid-closed state is hooked by the lid-opening hook. Thus, when the jig mechanism continues to advance, the lid of the lid to be tested opens under the action of the lid-opening hook, completing the lid-opening operation of the lid to be tested.

[0010] Further, the jig mechanism includes a first track plate, which is provided with a bevel edge and is installed on both sides of the jig mechanism. It is used for the lid-closing member to move along the bevel edge of the first track plate when the jig mechanism advances or retracts, so that the lid-closing member descends or ascends.

[0011] In the above implementation process, the first track plate is arranged on both sides of the jig mechanism, and one of them is a bevel edge; when the jig mechanism retracts, the lid-closing member moves upward along the bevel edge of the first track plate, causing the lid-closing member to ascend. At this time, the lid of the lid to be tested in the open-lid state on the jig mechanism is blocked by the lid-closing member. When the jig mechanism continues to retract, the lid-closing member continues to ascend, and then the lid-closing of the lid to be tested is completed, simulating the real lid-closing action of the lid to be tested; when the jig mechanism advances, the lid-closing member moves downward along the bevel edge of the first track plate to complete the reset operation of the lid-closing member.

[0012] Further, the device further includes a top frame and a telescopic member. The top frame is installed on the base mechanism; the telescopic member is installed on the top frame and can be telescopically extended vertically. It is connected to the lid-closing member through a roller. The telescopic member is used for the lid-closing member to move along the bevel edge of the track plate through the roller when the jig mechanism advances or retracts, so as to lower or raise the lid-closing member.

[0013] In the above implementation process, the lid-opening member moves on the bevel edge of the first track plate through a roller and is arranged on the top frame through a telescopic member; when the jig mechanism advances or retracts, the lid-closing member makes a reciprocating up-and-down movement under the action of the bevel edge of the first track plate and the telescopic member, thus simulating the real usage action when the lid to be tested is closed.

[0014] Further, the device further includes a second track plate connected to the lid opening member. The second track plate has an inclined side, and is configured to contact the first track plate through the inclined side of the second track plate when the jig mechanism moves forward or backward, so as to lift or lower the lid opening member.

[0015] In the above implementation process, the lid opening member moves under the action of the inclined side of the second track plate and the first track plate; when the jig mechanism moves forward, the first track plate lifts the second track plate along the inclined side of the second track plate; when the jig mechanism moves backward, the first track plate lowers the position of the second track plate along the inclined side of the second track plate. In the above manner, the lid opening member reciprocates under the action of the first track plate and the second track plate, simulating the real use action when the lid of the to-be-tested lid is opened.

[0016] Further, the device further includes a capping roller, which is disposed behind the lid closing member and is configured to cap the to-be-tested lid when the jig mechanism moves backward, so as to fasten the lid of the to-be-tested lid.

[0017] In the above implementation process, the capping roller is disposed behind the lid closing member. When the jig mechanism moves backward, first the lid closing member closes the to-be-tested lid, and then the capping roller caps the to-be-tested lid, so that the lid of the to-be-tested lid is fastened; in the above manner, after the to-be-tested lid is fully closed and then opened, the real use process of the to-be-tested lid is better simulated, thereby improving the test accuracy of the flip fatigue test.

[0018] Further, the device further includes a display screen, which is configured to display the operating parameters of the device.

[0019] In the above implementation process, the controller can control the operating parameters of the flip fatigue test device, and the display screen can display the operating parameters of the flip fatigue test device, so as to better monitor the operating process of the device and improve the practicability and reliability.

[0020] Further, the device further includes a stop switch, which is configured to control the operation of the device.

[0021] In the above implementation process, the stop switch is an emergency switch. Thus, when an emergency occurs, the stop switch can stop the operation of the flip fatigue test device, improving the safety and reliability of the flip fatigue test device.

[0022] Further, the device further includes a driving mechanism, which is configured to drive the jig mechanism to move forward or backward.

[0023] In the above implementation process, the driving mechanism can be a stepper motor, and the operating displacement and speed can be adjusted parametrically, thereby improving the practicability of the flip fatigue test device.

Through the combination of a flip piece and a closing piece, the curve formed by their movement is matched with the curve of flip opening and closing, so as to better simulate the use process of flip products. Compared with the existing manual test or other flip test instruments, this flip fatigue test device can achieve the technical effects of cost savings, while improving the test efficiency and test accuracy.

[0037] Please refer to Figure 1 and Figure 2 , Figure 1 which is the front structure diagram of a flip fatigue test device provided by an embodiment of this application, Figure 2 which is the back structure diagram of a flip fatigue test device provided by an embodiment of this application. This flip fatigue device includes a base mechanism 10, a fixture mechanism 20, a flip mechanism 30, a driving mechanism 50, and a to-be-tested cover 40, a driving mechanism 50.

[0038] In some embodiments, the lid 40 to be tested can be a plastic lid for toothpaste, cosmetics, etc. The lid 40 to be tested can be opened or closed, and can be fastened when closed.

[0039] Exemplarily, the base mechanism 10 is the base of the flip lid fatigue test device. The base mechanism 10 includes a base box body 11 and a platform bottom plate 12. A jig mechanism 20 and a flip lid mechanism 30 are installed on the platform bottom plate 12.

[0040] In some embodiments, a stop switch 13, a reset switch 14, and a display screen 15 are installed on the base box body 11. Among them, the stop switch 13 can immediately stop the operation of the flip lid fatigue test device in case of an emergency, thereby effectively protecting the device and the product to be tested, and improving the safety and reliability of the flip lid fatigue test device. The reset switch 14 can perform a reset operation when the flip lid fatigue test device stops due to a fault. The display screen 15 is a touch display screen. The operator can set corresponding operating parameters on the display screen 15, such as: device operating speed, number of opening and closing times, etc., and display them on the display screen 15, so as to facilitate the debugging of the flip lid fatigue test device to meet different flip lid fatigue test requirements and improve the practicability of the flip lid fatigue test device.

[0041] In some embodiments, a sliding guide rail 16 is installed on the platform bottom plate 12. The jig mechanism 20 can slide back and forth on the sliding guide rail 16, so that the jig mechanism 20 can move forward or backward along the base mechanism 10, and then perform an opening or closing operation on the lid 40 to be tested.

[0042] Exemplarily, the jig mechanism 20 is installed on the base mechanism 10 and can move forward or backward along the base mechanism 10. A fixing member 21 for fixing the lid 40 to be tested is provided on the jig mechanism 20.

[0043] In some embodiments, a plurality of fixing members 21 can be provided on the jig mechanism 20, and a plurality of lids 40 to be tested can be fixed on the plurality of fixing members 21. Thus, when the jig mechanism 20 moves forward or backward along the base mechanism 10, the plurality of lids 40 to be tested perform opening or closing operations uniformly, that is, fatigue tests are performed on the plurality of lids 40 to be tested, thereby greatly improving the test efficiency of the flip lid fatigue test device.

[0044] In some embodiments, the fixture mechanism 20 includes a first track plate 22, which is installed on both sides of the fixture mechanism 20, and the first track plates 22 on both sides of the fixture mechanism 20 are mirror-symmetrical; a hypotenuse is provided on the first track plate 22, so that when the fixture mechanism 20 moves forward or backward, the lid-closing member 31 on the flip cover mechanism 30 can move along the hypotenuse on the first track plate 22, thereby lowering or raising the lid-closing member 31. As an example, when the fixture mechanism 20 moves backward, the lid-closing member 31 is raised to complete the lid-closing operation of the to-be-tested lid 40; when the fixture mechanism 20 moves forward, the lid-closing member 31 is lowered to complete the reset operation of the lid-closing member 31. In the above manner, when the fixture mechanism 20 moves backward, the to-be-tested lid 40 moves backward and the lid-closing member 31 is raised to complete the lid-closing operation of the to-be-tested lid 40 in the open-lid state, which well simulates the curve of the to-be-tested lid 40 during lid-closing; thus, the curve formed by the movement of the lid-closing member 31 matches the curve of lid-closing, achieving a perfect simulation of the flip cover usage process.

[0045] Exemplarily, the flip cover mechanism 30 includes a lid-closing member 31 and an open-lid member 32. The lid-closing member 31 and the open-lid member 32 are arranged above the fixture mechanism 20. The lid-closing member 31 is used to close the to-be-tested lid 40 when the fixture mechanism 20 moves backward, and the open-lid member 32 is used to open the to-be-tested lid 40 when the fixture mechanism 20 moves forward.

[0046] In some embodiments, the flip cover fatigue test device further includes a second track plate 33, which is connected to the open-lid member 32. The second track plate 33 has a hypotenuse for raising or lowering the open-lid member 32 when the fixture mechanism 20 moves forward or backward by contacting the hypotenuse of the second track plate 33 with the first track plate 22. As an example, when the fixture mechanism 20 moves forward, the first track plate 22 raises the second track plate 33 along the hypotenuse of the second track plate 33; when the fixture mechanism 20 moves backward, the first track plate 22 lowers the second track plate 33 along the hypotenuse of the second track plate 33. In the above manner, when the fixture mechanism 20 moves forward, the open-lid member 32 connected to the second track plate 33 is raised to open the to-be-tested lid 40 in the closed-lid state, which well simulates the curve of the to-be-tested lid 40 during lid-opening; thus, the curve formed by the movement of the open-lid member 32 matches the curve of lid-opening, achieving a perfect simulation of the flip cover usage process.

[0047] In some embodiments, the flip cover fatigue test device further includes a first adjustment mechanism 35, which is connected to the open-lid member 32 and is used to adjust the height of the open-lid member 32 so as to adapt to to-be-tested lids 40 of different sizes and improve the practicability of the flip cover fatigue test device.

[0048] In some embodiments, the flip cover fatigue test device further includes a capping roller 60. The capping roller 60 is disposed behind the cover closing member 31 and is used to cap the test cover member 40 when the jig mechanism 20 retracts, so as to fasten the lid of the test cover member 40. In the above manner, after the test cover member 40 is fully closed and then opened, the actual usage process of the test cover member can be better simulated, and the test accuracy of the flip cover fatigue test can be improved.

[0049] In some embodiments, the flip cover fatigue test device further includes a second adjustment mechanism 36; the second adjustment mechanism 36 is connected to the capping roller 60 and can adjust the height of the capping roller 60, so that the capping roller 60 can be applicable to flip covers of different sizes, improving the practicality.

[0050] Exemplarily, the driving mechanism 50 is connected to the jig mechanism 20 and is used to drive the jig mechanism 20 to advance or retract along the sliding guide rail 16.

[0051] In some embodiments, the driving mechanism 50 includes a driving motor 51, a lead screw base 52, and a ball screw 53. The ball screw 53 is connected to the jig mechanism 20 through the lead screw base 52 and is a transmission element between the driving motor 51 and the jig mechanism 20; wherein, the ball screw 53 can convert the rotary motion of the driving motor 51 into a linear motion, thereby driving the jig mechanism 20 to advance or retract along the sliding guide rail 16.

[0052] Exemplarily, the flip cover fatigue test device further includes a top frame 70.

[0053] Exemplarily, the top frame 70 is installed on the platform bottom plate 12, and the telescopic member 312 is installed on the top frame 70.

[0054] Please refer to Figure 3 , Figure 3 which is a structural diagram of a cover closing member provided by an embodiment of the present application. The cover closing member 31 includes a cover closing rod 311 and a telescopic member 312.

[0055] Exemplarily, the cover closing member 31 includes a cover closing rod 311, and the cover closing rod 311 is used to flip the test cover member 40 in the open cover state when the jig mechanism 20 retracts.

[0056] Exemplarily, the cover closing rod can move along the hypotenuse of the first track plate 22.

[0057] Exemplarily, the telescopic member 312 is installed on the top frame 70 and can be vertically telescoped. It is connected to the cover closing member 31 through rollers. The telescopic member 312 is used to move along the hypotenuse of the first track plate 22 through the rollers when the jig mechanism 20 advances or retracts, so as to lower or lift the cover closing member 31.

[0058] Please refer to Figure 4 , Figure 4The side view structural diagram of a flip fatigue test device provided by an embodiment of the present application.

[0059] Exemplarily, the driving mechanism 50 drives the fixture mechanism 20 to continuously move forward and backward, thereby continuously performing opening and closing operations on the test cover 40 on the fixture mechanism 20, and performing a fatigue test on the test cover 40.

[0060] In some implementation scenarios, when the flip fatigue test device is powered on, the test cover 40 is in an open state; the driving mechanism 50 drives the fixture mechanism 20 to retreat, the hypotenuse of the first track plate 22 contacts the telescopic member 312, and the roller moves upward along the hypotenuse of the first track plate 22, thereby driving the closing rod 311 to move upward. The upward movement of the closing rod 311 cooperates with the backward movement of the fixture mechanism 20 at this time to simulate the actual closing action of the test cover 40 and complete the closing of the test cover 40.

[0061] After the test cover 40 is closed by the closing member 31, the driving mechanism 50 continues to drive the fixture mechanism 20 to retreat, and the test cover 40 passes through the capping roller 60. The capping roller 60 performs a capping operation on the test cover, thereby fastening the lid of the test cover 40.

[0062] After the lid of the test cover 40 is fastened, the fixture mechanism 20 moves forward under the drive of the driving mechanism 50. The roller on the telescopic member 312 moves downward along the hypotenuse of the first track plate 22, thereby driving the closing rod 311 to move downward to complete the reset operation of the closing member 31; at the same time, the first track plate 22 contacts the hypotenuse of the second track plate 33 and lifts the second track plate 33, thereby lifting the opening member 32. The opening hook on the opening member 32 hooks the lid of the test cover 40; the upward movement of the opening member 32 cooperates with the forward movement of the fixture mechanism 20 at this time to simulate the actual opening action of the test cover 40 and complete the opening of the test cover 40.

[0063] After the lid of the test cover 40 is opened, the fixture mechanism 20 moves backward under the drive of the driving mechanism 50. The first track plate 22 contacts the hypotenuse of the second track plate 33 and lowers the second track plate 33, thereby lowering the opening member 32 to complete the reset operation of the opening member 32. Through the above method, a flip process of the test cover 40 is completed; thus, during the operation of the flip fatigue test device, the actions of the test cover 40 during actual use are simulated, and the curve formed by its movement matches the curve of the flip opening and closing, achieving the technical effect of simulating the flip use process of the test cover 40, thereby improving the test efficiency and test accuracy.
